PERTUMBUHAN DAN PRODUKSI BEBERAPA VARIETAS TANAMAN JAGUNG (Zea mays l.) DENGAN PEMBERIAN BERBAGAI DOSIS PUPUK ORGANIK CAIR DAN PUPUK KANDANG

Abstract

This research aims to determine the effect of varieties and fertilization combinations between liquid organic fertilizer and manure and the interaction of both that provide the best growth and production. This research was carried out in the Religion Agro Tourism garden in Padanglampe Village, Ma'rang District, Pangkajene Regency and the Islands of South Sulawesi Province, from January to May 2020. The experimental design used was a split plot design with two factors, namely variety and a combination of liquid organic fertilizer with manure, variety as the main factor consisted of three levels, namely BISI-18 variety, NASA29 variety and Pertiwi-5 variety. The combination of liquid organic fertilizer with manure as a plot consists of four levels, namely Control, a combination of liquid organic fertilizer with chicken manure, a combination of liquid organic fertilizer with cow manure, a combination of liquid organic fertilizer with manure and cow manure . Data were analyzed by variance using the F Test. The difference in the mean value of the treatment would be tested with Tukey's HSD (honestly significant difference) test at the 0.05% level.The results showed that (1) The treatment of three varieties did not significantly affect all observed parameters. But the Pertiwi-5 variety tends to be the best compared to other varieties. (2) The treatment of fertilizer combination between liquid organic fertilizer and manure significantly influences all of the monitoring parameters. The combination of liquid organic fertilizer 5cc / l. Water with Chicken manure 15 tons / ha and Cow manure 15 tons / ha tend to have a pretty good effect, by showing the dry shell weight per hectare of 8.75 tons / ha. (3) The interaction between varieties with a combination of liquid organic fertilizer and manure does not significantly affect all observation parameters. But the interaction between Pertiwi-5 varieties with a combination of liquid organic fertilizer 5cc / l. Water with Chicken manure 15 tons / ha and Cow manure 15 tons / ha tend to be the best compared to other interactions
